Definitions

  • the present invention relates to a disc recording/reproducing apparatus, and more particularly to a disc recording/reproducing apparatus suitable for controlling the apparatus or other external devices in accordance with control information recorded in a U-TOC area of a disc, the U-TOC area being a table of contents (TOC) area in which a user writes data.
  • a disc recording/reproducing apparatus suitable for controlling the apparatus or other external devices in accordance with control information recorded in a U-TOC area of a disc, the U-TOC area being a table of contents (TOC) area in which a user writes data.
  • TOC table of contents
  • a recordable MD disc has a spiral groove engraved in the record area of the disc.
  • the engraved spiral groove has a swell so that a swell frequency of 22.05 kHz can be detected when the disc rotates at a standard rotation speed. Therefore, the rotation of MD is controlled by maintaining the detected frequency to be 22.05 kHz.
  • the swell is FM modulated by address information at the deviation frequency of 1 kHz. This address information is used to detect a particular position of the spiral groove.
  • a logical access is executed in units of a cluster containing 36 sectors. Namely, the address of a sector is represented by a 16-bit cluster address and an 8-bit sector address.
  • an address (11FFH : 1FH) indicates the cluster address of 11FFH and the offset sector address 1FH of the cluster at 11FFH.
  • the disc area of a recordable MD includes, as shown in Fig.3, a lead-in area, a U-TOC area, and a recordable user area.
  • a music program is recorded in the recordable user area.
  • TNO-1 to TNO-255 are identifiers to be assigned to a plurality of music programs. For example, if a music program TNO-5 is recorded in the region from a start address 1F0BH : 0AH to an end address 2A2AH : 2BH, the identifier TNO-5 and its associated start address are stored in section 0 of the U-TOC area.
  • the identifiers and the music program names are stored in section 1 of the U-TOC area, as illustrated in Fig.4.
  • the U-TOC is therefore an information management table for music programs stored in the recordable user area.
  • ASCII code characters can be recorded in sector 1 of the U-TOC area and added to each TNO.
  • character information recorded in sector 1 of the U-TOC area of an MD has been used only for displaying character information on the display unit of the apparatus.
  • EP-A-0406021 discloses a disc recording and reproducing device.
  • the known device may be operated in a password mode in which read and write protections are available. To this end, read and/or write protection control codes are recorded in the TOC area.
  • the password mode the device provides for read or write protection, respectively, if the respective code is detected in the TOC area of a disc.
  • the present invention has been made in consideration of the above circumstances. It is an object of the present invention to eliminate the conventional disadvantages and provide a disc recording/reproducing apparatus for controlling the apparatus or other devices connected to it during the record/reproduction of information, by using character information recorded in the U-TOC area.
  • a disc recording/reproducing apparatus for recording/reproducing information in/from a disc having a TOC area capable of recording a character in correspondence with a track number appended to the recorded information at a desired position in the disc, characterized in that it further comprises:
  • Said specific character may comprise first and second specific characters and said control signal may be formed by ordinary character or characters between the first and second specific characters.
  • the string of characters includes a music program title, and means are provided for displaying information read from the disc, including said title.
  • the external device may be an amplifier for musical signals, a digital signal processor for musical signals or a graphic equalizer for musical signals, wherein said control signals control a frequency characteristic of the graphic equalizer.
  • Fig.1 is a block diagram of a disc recording/reproducing apparatus according to an embodiment of the present invention.
  • Figs.2A to 2D shows TNOs and associated characters recorded in the U-TOC area, wherein Fig.2A illustrates the state of one TNO of a recorded program, Fig.2B illustrates the state of three TNOs of recorded programs, Fig.2C illustrates the state of three recorded TNOs and associated characters, and Fig.2D illustrates the state of one TOC and associated characters not deleted.
  • Fig.3 is a schematic diagram showing the structure of an MD.
  • Fig.4 shows examples of the contents of section 1 of the U-TOC area of an MD.
  • Fig.1 is a block diagram of a disc recording/reproducing apparatus according to an embodiment of the present invention.
  • Figs.2A to 2D shows TNOs and associated characters recorded in the U-TOC area
  • Fig.2A illustrates the state of one TNO of a recorded program
  • Fig.2B illustrates the state of three TNOs of recorded programs
  • Fig.2C illustrates the state of three recorded TNOs and associated characters
  • Fig.2D illustrates the state of one TOC and associated characters not deleted.
  • reference numeral 1 represents an MD record/reproduction unit for an MD (64 mm diameter) which is a rewritable disc.
  • the MD record/reproduction unit 1 includes a mechanism section for mechanically driving an MD, a control section for controlling the mechanism section, and a signal processing section for encoding or decoding a signal based upon an MD format.
  • the MD record/reproduction unit 1 is controlled by a controller 2 to execute record, reproduction, search, or other operations.
  • the MD record/reproduction unit 1 supplies the controller 2 with the information recorded in an MD and the information representing the operation state of the apparatus.
  • the controller 2 supplies a control signal to the MD record/reproduction unit 1, and receives information from an MD to store necessary information in a RAM 3.
  • the controller 2 reads data from RAM when necessary to display a time and characters and generate data for a search operation.
  • the controller 2 analyzes character codes to transfer control data to the MD record/reproduction unit 1 or to an external device control terminal 7.
  • Information read from an MD or the operation state of the MD record/reproduction unit 1 is displayed on a display unit 6 under the control of the controller 2, upon manipulation of a remote controller 4 or an operation key 5.
  • RAM 3 temporarily stores lead-in information and U-TOC information copied from an MD during the read/write operation under the control of the controller 2.
  • An external device control signal sent from the controller 2 is transferred via the external device control terminal 7 to external devices such as an amplifier and a graphic device connected to the MD disc recording/reproducing apparatus.
  • a D/A controller 8 converts a digital signal reproduced by the MD record/reproduction unit 11 into an analog signal which is outputted to an analog amplifier (not shown).
  • An A/D converter 9 converts an analog signal such as an externally inputted musical program into a digital signal.
  • An MD is loaded on the MD disc recording/reproducing apparatus shown in Fig.1.
  • the remote controller 4 or the operation key 5 is manipulated to instruct the controller 2 to record a certain number of musical programs.
  • the controller 2 instructs the MD record/reproduction unit 1 to record musical signals supplied from the A/D converter 9.
  • the controller 2 calculates the address of each delimiter and stores a corresponding TNO, e.g., TNO-1 in RAM 3, as shown in Fig.2B.
  • the controller 2 When it is instructed to write a title (program name) and other characters to be added to each TNO, by manipulating the remote controller 4 or operation key 5, the controller 2 writes the program name and characters added to each TNO in RAM 3 at the area corresponding to each TNO.
  • the added characters are assigned particular meanings. For example, characters inserted between "@" and “%” are used as control codes.
  • the character immediately after "@” is a control code for its own MD disc recording/reproducing apparatus, and the second and following characters are a control code for other devices.
  • the controller 2 accesses RAM 3 to read the start address information and character codes for TNO-1 and instructs the MD record/reproduction unit 1 to reproduce the musical program of TNO-1.
  • the controller 2 also analyzes the external device control code "G6" and outputs a corresponding control signal from the external device control terminal 7.
  • the controller 2 accesses RAM 3 to read the start address information and character codes for TNO-2 and instructs the MD record/reproduction unit 1 to reproduce the musical program of TNO-2.
  • the controller 2 also analyzes the external device control code added to TNO-2 after sending a signal for canceling the previous external device control signal. Then, the controller 2 makes the display 6 to display the title "BAD" for TNO-2, and sends via the terminal 7 the new external device control signal for setting the fifth sound field mode to DSP as the external device.
  • the controller 2 accesses RAM 3 to read the control codes added to respective TNOs, and erases the musical programs of TNO-2 and TNO-3 excepting the musical program of TNO-1 because of the erase inhibition code "#". Even if a new musical program is to be recorded in the area of TNO-1, this new musical program is recorded in the area next to TNO-1 without erasing the program of TNO-1.
  • the controller 2 When it is instructed to unload the MD, by manipulating the remote controller 4 or operation key 5, the controller 2 sends a signal for unloading the MD after writing the U-TOC information at that time to the MD, to the MD record/reproduction unit 1. Upon reception of this signal, the MD record/reproduction unit 1 records the U-TOC information in the MD at the U-TOC area, and thereafter ejects the MD out of the apparatus.
  • control codes of particular characters are used for the MD recording/reproducing apparatus and other devices.
  • the invention is not limited to the embodiment only, but such control codes of particular characters may be adapted to be neglected by setting a "control code inhibition" mode to the MD recording/reproducing apparatus.
  • a custom code may be used to neglect the control code if the same custom code is not entered.
  • the apparatus can be controlled by the control information added to each TNO and recorded on the disc. For example, if the erase inhibition code is added, the musical program with this code is prevented from being erased inadvertently.
  • Other devices connected to the disc recording/reproducing apparatus can be controlled by the control information added to each TNO, such as the control of the frequency characteristic of a graphic equalizer of a sound synthesizer, the control of the sound field of DSP, and the control of Dolby Pro-logic reproduction. Accordingly, a user is not necessary to arrange the settings of each external device so as to match each musical program, providing the user with a comfortable and relaxed mood for listening to musical programs.
